OTTO ZWIETUSGH, OF MILXVAUKEE, XVISCONSIN.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 336,463, dated February 16, 1886.

Application filed February 13, 1884. Serial No. 120,659.

To all whom it may concern.-

Be it known that I, OTTO ZwIETUscH, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certian new and useful Improvements in Bottle- Stoppers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to that class of stoppers especially adapted to bottles containing effervescent waters or other liquids; and it consists in certain peculiarities of construction, as will berhereinafter described with reference to the accompanying drawings, in which Figure 1 represents a vertic l sectional View of my invention, and Figs. 2 and 3 similar views showing modified forms.

A is the head of the bottle; B, the drafttube; O, the supporting flange, and D the rubber washer placed between said flange C and the bottle-head A, which washer serves both as a packing between the bottle-head A and the flange O, and as a seat, F, for the stopper or valve E, the opening in said washer D corresponding in size to that of the lower end of tube B, and being somewhat smaller than the diameter of stopper or valve E.

G is the valve-stem,which enters the tube B above the flange G, and extends up through and out of a casing formed integral with the draft-tube, and is directly connected to a thumb-lever, H, fulcrumed to a projection, (in, upon said draft tube. The casing formed integral with the draft tube serves to contain a spring, I, the upper end of which impinges directly upon the thumb-lever to antomatically close and keep closed the stopper or valve E when pressure is removed from said lever.

The device in Fig. 2 differs from that in (No model.)

Fig. 1 in that the nozzle B is perpendicular, that the valve-seat F is inclined, and the stopper E has a rubber washer, and in that the washer D serves only as a packing between flange O and bottle-head A.

Fig. 3 differs from Fig. 1 only in that the tube and the stem are both inclined.

Thedesirable features in draft-nozzles of material, and the ball is preferably made of g g1ass,with the stem inserted by any suit-able means.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

'Ihe spring-valve bott-lestopper herein described, consisting of an integrally-formed draft tube having an internal diameter equal to that of the valve-opening, springcasing, and supporting-flange, a valve provided with a stem, at thumblever fulcrumed to the draft tube and directly connected to the valve-stem, a spring located, as shown, with its upper end impinging against the thumb-lever, and a washer or packing pr0- vided with an opening forming a seat for the valve, all arranged and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county ot'Milwaukee and State of Wiscoir sin, in the presence of two witnesses.

OTTO ZWIETUSOH.
